I am trying to get the name of a white flowering shrub. It is low growing (1 - 2 feet high) and about 3 feet wide. I have attached two pictures. We live in SE Pennsylvania.

That looks like a Deutzia to me. Mine are just starting to bloom now.

phyllisrec What a lovely shrub. I would like to have one. I will follow so maybe I can find out what it is

Some deutzias can be quite tall, be sure to get one of the shorter clones if that's what you want. 'nikko' is one that I grow that 's short.
